Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: May 5, 2023

Increasing the concentration of an element in edible produce (i.e., biofortification) can mitigate deficiency humans. Sprouts are small but popular part healthy diets providing vitamins and essential elements throughout year. Element composition sprouts easily be amended, e.g., by soaking grains element-rich solution before germination (grain-priming). In addition, pre-treatment to improve translocation from into grain may further enhance sprout. Cold plasma technique could provide such solution, as it increases wettability water uptake grains. Grains common buckwheat (Fogopyrum esculentum Moench) were pre-treated/ untreated with cold soaked ZnCl2 solution/pure water. Germination tests, α-amylase activity, hydrophilic properties assessed. tissues was assessed micro-particle-induced-X-ray emission X-ray fluorescence spectroscopy, respectively.

Plant biostimulants in ornamentals: Enhancing growth and stress tolerance

Advances in Horticultural Science, Journal Year: 2024, Volume and Issue: 38(2), P. 211 - 222

Published: July 1, 2024

Researchers have recently sought a comprehensive strategy to reduce the harmful effects of synthetic chemicals in agricultural production improve productivity and quality. Biostimulants benefit plants by protecting soil water resources eliminating adverse environmental from pesticides chemical fertilizers. Plant biostimulants, also called bioactivators, are becoming increasingly well-liked sector due their capacity boost plant’s growth rate increase its resistance stress. frequently used because they can crop quality, nutrient assimilation, rate, stress tolerance. This article thoroughly examines biostimulants’ on ornamental plants, concentrating ability withstand stressors. Prior studies demonstrated that combination non-pathogenic microbes, protein hydrolysates, humic fulvic acids, algal extracts benefits plants. review’s main aims raising yield, enhancing uptake, photosynthesis, shielding biotic abiotic The role biostimulants more resilient sustainable farming practices is covered

From seed to sprout: Unveiling the potential of non-thermal plasma for optimizing cucumber growth

Heliyon, Journal Year: 2023, Volume and Issue: 9(11), P. e21460 - e21460

Published: Oct. 29, 2023

Numerous strategies for enhancing seed germination and growth have been employed over the decades. Despite these advancements, there continues to be a demand more effective techniques, driven by growing global population. Recently, various forms of non-thermal atmospheric pressure plasma garnered attention as environmentally friendly, safe, cost-effective methods enhance agricultural food sectors. This study explores remarkable impact (NTP) treatment on cucumber (Cucumis sativus L.) germination.A cost-effective, custom-designed power supply operating at line frequency was used treating seeds, with exposure times ranging from 1 7 min. Various parameters, including water contact angle measurements, mass loss, imbibition rate, seedling length, were evaluated assess germination.Cucumber seeds exposed NTP 3 min 5 durations showed significant improvements, notably 57.9 ± 4.25 % higher final percentage, 14.5 3.75 reduced mean time, 90.6 4.64 increase in index compared control. These results suggest that enhanced coat permeability, triggered essential biochemical processes, expedited absorption nutrient assimilation, ultimately fostering faster synchronized germination.Our findings underscore potential an innovative approach improving practices.
